Oranga Tamariki says there's been an increase in emotional abuse of children returning to their parents, and physical harm between children in its residences.
The agency's Safety in Care report for the year ending June 2023 shows 9% of children in its care were harmed.
That's up from 5.6% in 2019.
Oranga Tamariki's Nicolette Dickson told Mike Hosking that in the past, harm children have experienced in care has probably gone undetected.
She says what's really difficult is when children are open and honest but aren't believed and action isn't taken, which is why Oranga Tamariki reports on this.
